Doc Text:
Cause: Removing the image registry on OpenStack (swift) when content has already been written to the storage. Consequence: Storage for image registry was not being removed and an error was logged (409 http return code). Fix: Removed the storage content before removing the storage solved the issue. Result: Now by removing the internal registry the operator removes its storage completely.
